An environmental health professional performs numerous job functions that have an impact on everyone's health and lifestyle. Their work is to prevent death and illness from environmentally related disease and injury. Moreover, the quality and safety of their air, food, water, and the infrastructure that supports vital environmental health services are one of the indicators separated many developed countries from undeveloped countries. This paper, environmental health professional in developed countries including the United State of America, United Kingdom, Canada, and Australia were discussed. It was revealed that the Registration of Environmental Health Specialist/Sanitarians is a process that certifies the applicant has been found by the certifying body of each state/country to meet the qualifications to protect environmental health. The result of these reviews indicates that competencies of Environmental Health Officers (EHOs) of all selected developed countries are focused on facility and system inspections and compliance and enforcement of environmental health laws. Moreover, risk assessment and management, investigation, monitor and control, and promoting environmental and public health awareness are appeared in some countries. Thus, the experiences in selected developed countries for certification of Environmental Health Specialist or sanitarian could be used as a guideline for environmental health professional development in other countries.

A citizen complaint presented to the Commission for Environmental Cooperation (CEC) of North America is a non-binding mechanism used by civil society to denounce incompliance with US., Canadian, and Mexican environmental legislation. Using a data base of citizens' complaints (1996-2012), this article offers an evaluation of the mechanism in three areas: a) perceptible influence on the three North American governments; b) performance and influence on sub-national levels; and c) patterns of historic evolution.

Many industries are required to monitor themselves in meeting regulatory policies intended to protect the environment. Self-reporting of environmental performance can place the cost of monitoring on companies rather than taxpayers, but there are obvious risks of bias, often addressed through external audits or inspections. Surprisingly, there have been relatively few empirical analyses of bias in industry self-reported data. Here, we test for bias in reporting of environmental compliance data using a unique data set from Canadian salmon farms, where companies monitor the number of parasitic sea lice on fish in open sea pens, in order to minimize impacts on wild fish in surrounding waters. We fit a hierarchical population-dynamics model to these sea-louse count data using a Bayesian approach. We found that the industry's monthly counts of two sea-louse species, Caligus clemensi and Lepeophtheirus salmonis, increased by a factor of 1.95 (95% credible interval: 1.57, 2.42) and 1.18 (1.06, 1.31), respectively, in months when counts were audited by the federal fisheries department. Consequently, industry sea-louse counts are less likely to trigger costly but mandated delousing treatments intended to avoid sea-louse epidemics in wild juvenile salmon. These results highlight the potential for combining external audits of industry self-reported data with analyses of their reporting to maintain compliance with regulations, achieve intended conservation goals, and build public confidence in the process., (© 2020 by the Ecological Society of America.)
